Generally agree. Read Rainbow's End for an example of what reduced friction UI is like for AR. But it is enabled by input and display devices that are several generations ahead. Heck, even Cyberpunk 2077 is somewhat interesting in this regard. I started with a Corpo character and realized the persistent screen elements with a news ticker, some other data etc were interesting in a game world I knew nothing about. I imagine having extremely limited but immediately present text overlays would be exceptionally useful to replace my phone or watch if the device enabling it was of a sufficiently unassuming form factor that didn't take work to use. If Apple can give me the equivalent of what airpods did you headphones with cords but for smartphones, even if in an extremely limited capacity to just say, iMessage at first, that would be huge. Then give me a haptic ring I can fidget with that, when combined with a purpose built virtual keyboard, can do text entry, and that is a killer app IMHO.
